Blow By Oil

[Goat150]

Hi,
I'm a new member of Skymaster Owners
and Pilots. And I hope I'm doing this right?
The 337H I have I has a 410 Hr Front engine and a 25 Hrs on the rebuilt rear that I paid to have done.

My question is I never had engine's with so much Blow By, The front engine is keeping the under side very oiley, and the rear engine I ran the blow by hose down and out by the fuel drain lines, just to keep the oil off the rear of the plane.
I've been told by two A/Ps that this is normal and to drop the oil down to six qts.
I'v done that and I guess it helped a little.
But I hate a oil leak and it's so hard to keep the plane clean.
Does any other owners have any thought.
Thanks
Mark
